How this service works
Change watch for is ip vercel: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current is-Vercel boolean result for the IP, a changed true/false flag comparing against the previous check (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the IP status was last observed.
Example use cases
Detect Vercel infrastructure migration
“Keep an eye on 104.21.48.1 for me — alert me if it stops being classified as a Vercel IP so I know when that service has migrated away from Vercel.”
Monitor competitor's CDN changes
“I want to know if 76.76.21.98 changes its Vercel status — check it regularly and tell me the exact fields that flipped and when it was last seen.”
Track newly Vercel-hosted IP
“Start watching 34.120.54.200 and notify me the moment it starts showing up as a Vercel IP — include what changed and the before/after values.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/is/vercel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes in Vercel IP classification over time rather than just a one-shot lookup. It is ideal for scheduled monitoring workflows where you want to be alerted the moment an IP moves onto or off of Vercel's infrastructure. Prefer it over a plain is-ip-vercel check when diffing matters — you get the before/after values and a changed flag automatically without managing state yourself.
Side effects
- Invalid or malformed IP address returns an error
- IP not previously checked results in no comparison data (first-run, no diff available)
- Previous result older than 90 days has been purged, so no historical comparison is possible
- Network connectivity issues may prevent the underlying Vercel IP range lookup
- Payment failure (x402) results in 402 response and no check performed
